Step-by-step explanation:

A negatively skewed distribution means that the distribution curve doesn't fall evenly on both sides of the median, but stretches out further to the low end. If the values above the median are only slightly above the median, but those below it could be far below it, the average (mean) will be below the median. If the mean (average) is 68, then the median must be above it, or 72.

The waiting time to ride a roller coaster is 20 minutes when 150 people are in line. How long is the waiting time when 240 peopl

laiz [17]

Answer: The waiting time will be 32 minutes when 240 people in line.

Step-by-step explanation:

Let us assume that the waiting time is directly proportional to the number of people in the queue.

Equation of direct proportion between variables x and y : $\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}$

Put $x_1=20,\ y_1=150,\ y_2=150$ to find $x_2$ .

$\dfrac{20}{150}=\dfrac{x_2}{240}\\\\\Rightarrow\ x_2=\dfrac{20}{150}\times240\\\\\Rightarrow\ x_2=32$

Hence, the waiting time will be 32 minutes when 240 people in line.

Two accounts earn simple interest. The balance yy (in dollars) of Account A after xx years can be modeled by y=10x+500y=10x+500.

GrogVix [38]

1)
A has a greater principal

2)
Principal of A is $500, the principal of B is $400, so A's principal is greater by $100

3)
Annual interest rate of A:
10/500 x 100
interest rate of A = 2%
The interest rate of B is higher.

4)
B's annual interest rate is 5% and A's annual interest rate is 2%, so B's is higher by 3%.

What is the y-intercept and x-intercept for the equation -3x - 4 = -5y - 8

BARSIC [14]

Step-by-step explanation:

=> -3x - 4 = -5y - 8

=> 8 - 4 = 3x - 5y

=> 4 = 3x + (-5)y

=> 1 = (3x/4) + (-5y/4)

=> 1 = x/(4/3) + y/(-4/5)

Compare this with x/a + y/b = 1 where a and b are x & y intercepts.

Here,
